WebHowever, this notion changed drastically in the 1990s, with observations of cytoskeleton-like structures in several prokaryotes. Homologs of the main components of eukaryotic cytoskeletons, such as microtubules, microfilaments, and intermediate filaments, have been identified in bacteria and archaea. WebCollectively, this network of protein fibers is known as the cytoskeleton. There are three types of fibers within the cytoskeleton: microfilaments, intermediate filaments, and microtubules ( Figure ). Here, we will examine each.
